The guard plate 10 has objects inView, the invention consists in a tWo longitudinally arranged,comparatively 5 device of the class and for the purpose specinarrowapertures 18 disposed adjacent the lied, which is simple inconstruction, efi'icient corners and one side edge thereof and other inuse, and which is constructed as hereintransverse, narrow apertures 19adjacent the ft d ib d d l i ed, corner portions and other side edgethereof.

The invention is fully disclosed in the fol- The arrangement of theapertures 18-19 lowing specification, of which the accomwith respect tothe guard plate is such that panying drawing forms a part, in which thethe center of the apertures 18 will correseparate parts of myimprovement are desigspond in position on the plate 10 with respectnated by suitable reference characters in each' to the center of theapertures 19 so as to of the views, and in which: register with equallyspaced, cross-shaped Fig. l is a transverse, sectional view of aapertures 20 formed in the corner portions razor made according to myinvention with of the blade 17 so as to register with either part of theconstruction broken away; the pair of apertures 18-19 as well ascorresection being on the line 11 of Fig. 2. spondin g projecting lugs2122 arranged on Fig. 2 is a section on the line 22 of Fig. 1. the undersurface'of the cap 11 as clearly seen 9 Fig. 3 is a plan view of oneform of blade in Fig. 4 of the drawing. It will be underwhich I employ.stood that the lugs 21 have their wide faces Fig. 4 is a perspectiveview of the cap emarranged longitudinally of the cap whereas ployed inthe structure shown in Figs, 1 and the corresponding faces of the lugs22 are ar- 2 detached. ranged transversely of the cap. Fig. 5 is a viewsimilar to'Fig. 1, showing Centrally of the cap 11 is a downwardly amodification. projecting threaded stud 23 in connection Fig. 6 is asection on the line 6-6 of Fig. 5. with which the handle 12 has a screwthread- Fig. 7 is a bottom plan view of the cap ed engagement so as toclamp the blade 17 shown in 5 and 6. within and between the guard plate10 and mo Fig. 8 is a plan view of the blade employed cap 11 and wherebythe cap 11 may be detached for the removal of the blade wheneverdesired. Arranged centrally and longitudinally of the blade is anelongated aperture 2a through which the stud 23 is adapted to pass andwhich is also adapted to receive the guide lugs employed on the cap asseen in the structure shown in Figs. 5 and 6 of the drawing, thusadapting the blade shown in Fig. 3 to both forms of holders shown.

The structure shown in Figs. 5 and 6 dill'ers from that shown in Figs. 1and 2 simply in the arrangement of the lugs and apertures employed forkeying and alining the blade within the holder and to provide the meansfor distinguishing the dillerent sides and the corresponding differentedges of the blade. In these figures, the guard plate 10a instead ofhaving the apertures 1819, is provided with lugs 21a22a and the cap liewith apertures 18(z19a to receive said lugs. In this construction, it isalso preferred that the outer faces of the lugs 2la22a be curved toconform with the urvature on the outer face of the cap lie when theblade 25 is arranged between the cap and plate so as to provide a smoothouter surface on said cap.

The blade 25 is similar in all respects to the blade 23 except thatinstead of providing the elongated aperture 24, three apertures areemployed, namely a central aperture 26 and two apertures 27 arrangedadJacentthe ends of the blade and adapted to register with guide lugs 28on the inner face of the cap 11a. Said cap has a central screw threadedstud 29 similar tothe stud 23, which is in screw threaded engagementwith the handle 12o as clearly seen in Fig. 6 of the drawing. The cornerportions of the blade 25 have crossshaped apertures 20a similar in allrespects to the apertures 20 and adapted to register with the projectinglugs Zia-22a as will be apparent.

The guard plate 10a will also be provided with apertures 30 to receiveguide lugs 28. At this time, it will be understood that the lugs 28 andapertures 30 may also be employed in the structure shown in Figs. 1 and2. However, it is found that the arrangement of the apertures 2020a uponthe lugs 21-22 and 21a2 2a is sullicient {or the proper alinement of theblades 17-25 upon the respective holders. It will be apparent however,that in forming the apertures 20-20a, slight clearance will be providedto compensate for the fiexure of the blade so as not to exert any forceor pressure on the blade which would tend to crack orbreak the same.

By providing a razor blade of the class described and a holder with thelugs arranged in contrasting relation to each other on opposite sides ofthe holder, it is possible to designate to the user, the distinction ofone cutting edge from the other so that in the process of shaving, oneedge of the blade may be used for the first shaving strokes or in aeeaeowhat might be termed the rough shaving, whereas the other edge ma. beused in the final shaving strokes to pro uce a clean, close shave. Inthis way, longer life of the blade will result.

lhis type of blade and holder construction is especially adaptable foruse in holders of the class disclosed having the transverse grooves onthe upper face of the guard plate which facilitate the cleaning of therazor to remove the lather therefrom by simply loos ening the handle toa slight degree and placing the razor under a. stream of water so as topass through said grooves which form nozzle discharges facilitating theremoval of the lather. in other words, it is not essential that theblade be detached from the holder between several shaving operations. Inthis way, the user will be certain at all times to know by virtue of thedifferent lugs which constitute marking elements visible externally ofthe holder, just which cutting edge of the razor blade should be usedfirst.

Another distinctive feature of my invention resides in the fact that bycontrolling the attachement of the cap to the guard plate in such mannerthat the cap is capable of mounting on the plate in one position only,it will be possible and in fact desirable to modify the contour ordimensions of the guard fingers atv one side edge of the razor so as tocontrol and regulate the spacing of the cutting edge of the blade withrespect thereto to vary it as compared to that of the spacing of theopposite cutting edge with respect to its guard fingers. In thisconstruction, and especially in using a characterizing means fordistinguishing one side edge from the other, the user of the razor willknow at all times the side edge of the razor to be used for the initialshaving strokes as compared with the finishing shaving strokes.

It will he understood that my invention is not necessarily limited tothe particular type of razor blade holder herein shown and described,nor am I necessarily limited to the specific form and arrangement of thelugs herein disclosed and in like manner, the form of the aperturesprovided in the corner portions of the blade. Various other changes inand modifications of the construction herein disclosed may be madewithin the scope of the appended claims without departing from thespirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. A razor of the class described comprising a guard plate, a capadapted to be clamped on the upper face of the guard plate with a doubleedged blade disposed therebetween, the corner portions of said plate andi cap being provided one with elongated apertures and the other withprojecting bar-like lugs adapted to pass through said apertures andexposed externally of the razor, the lugs in the corner portions of oneside edge of the razor being arranged longitudinally of its cuttingedge, and the lugs in the corner portions of the other side thereofbeing arranged transversely.

2. A razor of the class described comprising a guard plate, a capdetachable with re spect to said plate and within and between which arazor blade is adapted to be clamped, and said plate being provided withprojecting lugs having flat sides and said cap with elongated aperturesto receive said lugs and through which said lugs are visible, said lugsand apertures being disposed adjacent the corner portions ofthe cap andplate, and the lugs at the corner portions. of one side of the razorbeing disposed with their flat sides substantially parallel to thecutting edge and at the other side with their flat sides perpendicularto the cutting edge.

8. A razor of the class described comprising a guard plate, a capdetachable with rospect to said plate and within and between which arazor blade is adapted to be clamped, and said plate being provided withprojecting lugs having fiat sides and said cap with edge of the razorbeing arranged transversely.

5. In razors of the class described an elon gated double edged blade thecorner portions of said blade adjacent the side edges thereof havingwithin the boundary edges of the blade transverse apertures andcentrally intersecting longitudinal apertures, the transverse aperturesof one side edge of the blade being in alinement with those at theopposite side edge thereof and the lon itudinal apertures at one end ofthe blade eing in alinement with those at the other end thereof.

In testimony that l claim the foregoing as my invention l have signed myname this 16th. day of January, 1931.
